Abstract
Potassium titanate, magnesium borate and calcium sulfate whisker modified non-metallic friction materials (designated as P, M and C) were prepared by compression moulding process. Results of physical test showed that the addition of whisker greatly improved mechanical properties and slightly increased thermal stability. Particularly, M exhibited the highest tensile strength and C showed the best thermal stability. The tribology properties were investigated against a special counterpart of wire rope under dry and grease lubrication conditions. Results showed that potassium titanate whisker improved the wear-resistance most, and calcium sulfate whisker increased the value and stability of friction coefficient most at high sliding speed.
